Richmond Fitness Club

Richmond Fitness Club is a proper sports facility just outside Chessington in Surrey - the sort of place locals actually use rather than tourists stumbling through. It's a full-service gym setup with what you'd expect: equipment, classes, swimming facilities. Nothing flashy, but it works.

If you're mid-holiday and desperate not to lose momentum with your fitness routine, this beats doing press-ups in your caravan. The classes tend to draw a regular crowd, which is either brilliant motivation or slightly intimidating depending on your mood. Swimming is the real draw for families - a decent pool and some actual structure to your day when you're getting cabin fever at the caravan site.

The place is straightforward to access if you're staying at Walton on Thames Camping and Caravanning Club Site, about six miles away. It's not the sort of destination you'd plan a day around unless you're genuinely keen on gym work, but as an add-on activity during a longer park holiday, it makes sense.

Website says richmondfitnessclub.co.uk for opening hours and pricing - worth ringing ahead because charges vary depending on whether you're a day visitor or member. Not free, but day passes are reasonable if you need the break from the outdoors.
